RO/DI vs plain RO

corwise · 01/19/2021, 05:59 PM

Moved to a small town in AZ a few years back and finally ready to start up a new tank. Trying to figure out the best way to get water. Nearest fish stores are in Tucson over an hour away, so trying to find a local solution instead of buying at a shop as I've always done in the past.
There some of those water stations set up around town that sell RO water at $1 a gal or so. Trying to figure out if "RO water" is good enough for corals or if I really need to have a home RO/DI canister system?
Currently planning on a 65 gal tank with sump so I know I'll be losing a gal a day or so to evaporation. My garage has a space for a work sink, is there any home RO/DI system that can plug into those pipes or do I need an actual faucet to hook into? Thanks much.

Dave, I hear that AZ water is THE WORST. Spectrapure is in AZ too.
Any system can use one of these on a cold water pipe ---
